In simple
cases *M*_{1}, from eq. (1), is a histogram equalization operator (for contrast
adjustment) or only the identity matrix, and *M*_{2} and *M*_{3}
represent raising each
point in the matrix to a power. Several variations that would
result in monochrome colormaps suitable especially for highlighting
linear, coherent shapes (fig. 6) can be imagined. If a more complex
colormap is desired, the three operators must be constructed by
transforming common RGB colormaps to NTSC, with the equation:

An example is provided in Figure 1 for Matlab's jet
colormap.
